Pene told him the haka referred to the current New Zealand soldiers being descendants of those who fought various campaigns around the world.

"It also elaborates further, into the various terrains the soldier fights in," he said.

After a demonstration of the haka, Mr Pene said: "So as you can see here your Royal Highness, it's a short and simple haka. And hopefully given the timeframe we have with you today, we'll get you to a good standard."

The prince who holds the ranking of captain in the British Army touched down in an an New Zealand Defence Force NH90 chopper. He was then asked to drive a Polaris All Terrain Vehicle across the base.

He drove the ATV across the base at high speed before bringing it to a halt with a small skid in the mud.

"Everything about that felt wrong," Harry said, referring to his tyre tracks across the lawn.

"I was waiting for someone to tell me to get off the grass."

Wearing the British Army uniform and a blue beret, he donned a helmet and pulled on a New Zealand military jacket before driving the vehicle to the base's hangi pits.
